2x and 8x+40 complementary angles
their sum is 180
2x+8x+40=180
10x=140
x=14
Answer:
Step-by-step explanation:
hello :
f(x) =-2x²+4x+1 Completing The Square : f(x) =2(x²+2x)+1
f(x) = -2((x²-2x+1)-1)+1
f(x) = -2((x-1)²-1)+1
f(x) =2(x-1)²+1 ... verex form when the vertex is (1,1)
the axis of symmetry is x=1
Simply cross multiply and simplify to get a = 11
